Therefore, how to create a green campus is worth paying more attention to. Some effective measures have been taken to create a “green campus”. Firstly, as university students, we should take part in environmental protection activities. Secondly, we should abide rules of saving natural resources, such as water and electricity. Thirdly, we might as well attend lectures on “sustainable development” so as to raise the awareness of environmental protection. As far as I am concerned, “green campus” will do good to both the campus and the whole society. However, it is worth noting that some people still havent realized this point. Therefore, we should give publicity to the importance of creating a “green campus” and try our best to solve these problems.二、 现象解释型 In modern society, 总述现象。The main reason for该现象is 原因1.

When we go shopping, in big supermarkets, we will always be provided with plastic bags for free. Moreover, most people have been used to using disposable plastic bags as containers for almost everything. As everyone sees, disposable plastic bags have brought great negative effects on our environment. For example, these plastic bags are the main source of white pollution. Whats more, plastic bags can not disappear by natural decomposition, so they will exist for a long time. Besides, some people throw them away casually after use because they are very cheap. From my point of view, limiting the use of disposable plastic bags is of great significance. For one thing, the ban on free plastic bags encourages people to use paper or cloth bags, which is favorable to the reduction of environmental pollution. For another, it can help increase the whole nations consciousness of the importance of environmental protection. To conclude, by limiting the use of disposable plastic bags, everyone can contribute some effort to the improvement of our environment.三、 对比选择型When it comes to 谈论主题, there is no complete agreement among people.

When it comes to whether the university campus should be open to tourists, there is no complete agreement among people. Some people take it for granted that university campus should embrace tourists across the country. However, others maintain that the university campus should be closed to tourists. Those people who hold the first opinion believe that refusing tourists is contradicting universities openness of spirit. In addition, they insist that no university has the right to reject tourists to enter its grounds because it is public land. However, still others think differently. In their opinion, too many tourists will add a burden to the security of the university. Besides, they argue that these tourists will destroy the quiet environment and influence students normal study. Weighing up these two arguments, I prefer the former opinion. For one thing, by visiting the university, high school students can experience the campus atmosphere and be stimulated to make a better preparation for the college entrance exam. For another, a university is a public place and should impart the spirit of openness. Considering these, I may reasonably conclude that the university campus should welcome all tourists.四、 观点论证型 Nowadays, there still exists +与论点相冲突想象. However+文章论点.
